State tax filing

At the screen 'Your CA taxes are ready to check' (screenshot), Continue past the long list of adjustments to 'Done with Adjustments' at the bottom. 

The next screen is 'Nonresident Adjustments'. Continue, and you get screens asking about taxable items in your Federal Return (first page is W-2 income), displaying the Federal Amount and with a blank field for the 'California Amount' (screenshot).

For self-employment income, continue to a screen titled 'California Business Income or Loss' that has your Federal amount filled in.  You would enter $0 for 'California Amount' (screenshot).
